Electrical PVC for potable water?

I am running 1/2 "water lines to a bathroom in the barn, I ran an additional 1" schedule 40 pvc for a later use spare. I want to use electical sweeps at each end so it can use it for water or wire depending on the need. Is there any health issues if it is used for drinking water?

You can not use electrical PVC for water.You can not use SCH 40 for potable
water.

I would not say you can not use SCH 40 for potable water, there are many states that allow it for cold water supply only. Illinois is one of them. Now electrical PVC pipe and fittings are not rated for plumbing use.

You can use PVC underground for potable water, it is only permitted above ground in some states. There is really nothing to be gained by using long sweeps in a water supply, only in drains where crud is passing through and could clog on a tight turn.

For elec conduit, the pressure rating is a problem and flexible PVC has plasticizers that give it flexibility. These leach out and can give water a plastic taste, supposedily non-toxic. Doesn't seem worth it to save a few bucks.

This is being used for a bathroom and shower in the barn, Any idea why it is not to be used for hot water? I already have it burried so I I will be using for both. It will be connected in my basement so I would prefer the connection dont come apart.
Thanks for all your input!

PVC is not rated for hot water , CPVC is rated for use with hot water. Standard PVC becomes pliable and will lose its shape when hot water is used in it.

First, PVC is not rated for hot water supply, as far as I know, ever. Then, 1/2" on a long supply will have LOTS of friction, and your flow and pressure will suffer. CPVC is allowed for hot. Both can get brittle as they age. You'd be much better served on a long run to run a bigger pipe, and, chose one with no underground connections.. The pipes designed for this are much more resilient, and if you lay it sort of from side to side of the trench, you won't risk damaging the pipe from expansion and contraction issues...your idea just isn't very good, and won't pass inspection, either.

Everything used/comes in contact with the water, in a potable water system must be approved to meet NSF Standard 61, or it is not permitted/allowed or used. That is federal law and followed by a states.

Sch 40 PVC is NSF standard 61 and is allowed in most areas under and above ground but codes disallow it inside a house. It is not approved for hot water use because its pressure rating is done at 73*f. For every x degree increase in temp you lose X psi.

Ronquick, you were correct in questioning your choice, so replace the 1/2" PVC which is probably too small due to friction loss for the distance, or use regular 1/2" sch 40 PVC elbows on it. Half inch sch 40 pvc is about equivalent to 3/4" CPVC or 3/4" copper because it is IPS (iron pipe size which maintains the ID, copper etc. is CTS (copper tubing size) and that maintains the OD, so the ID is smaller than IPS pipe.

Tell your buddy not to pressurize his. The best choice is a roll of 1" PE (polyethylene) pipe with one fitting on each end. I'd use 160 psi rated.

Thanks to everone for the info, I have decided to use the 1" schedule 40 with schedule 40 elbows for the cold water feed line and install a small hot water heater in the barn. I have ran 1/2 copper for the bathroom fixtures.

PVC has materials added to it to facilitate the manufacturing process. Grey electrical PVC has toxic heavy metals added to it, I believe I was told it was Lead , by a major manufacturer of pipe. DO NOT RUN POTABLE WATER THROUGH THIS PIPE.
